DIY Woodstove Boiler for In-Floor Heating

Here are the numbers for the wood stove boiler I made to heat the in-floor heating system in my office. Wood stove boilers are really efficient at heating water and very common in a lot of the world, like Europe and Australia, but they're almost unheard of most parts of the US.

The boiler I've designed for this build is a split between a water heater and a radiating wood stove, so the sides and back will be covered in a water jacket to heat the in-floor heating, and the front and top won't be covered, so they'll immediately radiate their heat directly into the room.

Here are the numbers from the test:
